[evolution-patches] A patch for e-table a11y bugs. (#310136 #310138)

[Li Yuan <Li Yuan Sun COM>]

Hi,

Here is a patch to fix #310136 and #310138. I don't know who is taking 
charge of e-table's a11y part now.
Please tell me and help me to review it.

Thank you very much.

Best Regards,
Li

+	Fixes #310136 #310138.
+	* e-table/gal-a11y-e-table-item.c: (eti_get_index_at),
+	(eti_get_row_at_index), (eti_get_n_rows), (eti_rows_inserted),
+	(eti_rows_deleted), (eti_header_structure_changed):
+	The first items of e-table are column-header. So we should add
+	number of columns when change (row, col) to index, or subtract
+	when change index to (row, col).
